Description
Technical Field
The invention relates to the technical field of building materials, in particular to a special machine-made sand composite material for a wallboard component and a preparation method thereof.
Background
In recent years, with the development of economy and the improvement of living standard of people, the requirements on building aesthetics and building safety are higher and higher. In order to meet the requirements of modern urban buildings, the assembly type buildings are rapidly advanced, and the assembly type building materials are driven to develop rapidly. The wall plate member is the foundation for realizing the assembly of modern residential buildings, so that the development of the prefabricated concrete wall plate member with good comprehensive performance for the assembly buildings is very important.
The performance of the prefabricated concrete wall panel member of the fabricated building is determined by concrete as a preparation material, the demand of the prefabricated concrete wall panel member is continuously increased along with the rapid development of the building industry, meanwhile, certain requirements are also required on the quality of the concrete, the requirements on the performance of the concrete are not limited to compressive strength, but the balance and coordination of comprehensive indexes such as the durability of the heavy concrete are further added on the basis of the standing strength. The requirements of various performance indexes of the concrete are more definite, detailed and concrete than before. The sand is an important material composed of concrete, along with the development of the construction industry and the attention on the quality of construction engineering, the quantity of the sand used in the construction market is larger and higher, and the qualified natural sand resources are less and less. Under the situation, the machine-made sand concrete enters the sight of people, and the machine-made sand concrete draws wide attention of people once appearing.
An important raw material of the machine-made sand concrete material is machine-made sand, and the machine-made sand fork is called artificial sand, is formed by removing soil, mining, mechanically crushing and screening rocks, and has nominal particle size smaller than 5 mm. The machine-made sand is broken, the particles of the machine-made sand are in an irregular shape, the stone is hard, the specific surface area of the machine-made sand is larger than that of river sand, the binding property is better, and the machine-made sand can form a better binding effect with cement. However, the mechanical sand has poor grain composition, more grains are larger than 2.5mm and smaller than 0.08mm, the workability of concrete is easily influenced, the appearance quality of the concrete is easily influenced, and the characteristics of multiple edges and rough surface of the mechanical sand cannot meet the workability of the concrete. Meanwhile, the mud powder contained in the machine-made sand is adsorbed on the surface of the sand, which may interfere with the binding action between the sand and the cement.
Chinese patent CN1792978A discloses a self-compacting concrete, which is prepared by mixing 100 parts of cement, 60-100 parts of fly ash, 5-20 parts of silica powder, 1-40 parts of other admixtures, tackifier, defoamer, polycarboxylic acid water reducing agent and the like, and preparing the concrete with the compressive strength of 50-60MPa for 28 days, wherein the other admixtures refer to mineral powder and limestone powder with the fineness of 100 meshes and below. However, the admixture adopts silica powder which is high in price and easy to be absorbed by human bodies, the coarse aggregate adopts natural coarse aggregate, and simultaneously, additives such as tackifier and the like which are not widely used are adopted. Although limestone powder is adopted in the patent, the coarse aggregate is all-natural coarse aggregate, and external agents such as silica powder and tackifier which are not widely used are also adopted, so that the cost of the concrete is higher, and the strength of the concrete is only C50 at the highest.
